Задача. На сторонах равностороннего треугольника 𝐴𝐵𝐶 отмечены равные отрезки 𝐴₁𝐴₂ = 𝐵₁𝐵₂ = 𝐶₁𝐶₂ так как показано на рисунке. Прямые 𝐴₁𝐶₂, 𝐶₁𝐵₂, 𝐵₁𝐴₂ образуют треугольник 𝑋𝑌𝑍. Докажите, что углы треугольника, составленного из отрезков 𝐴₁𝐶₂, 𝐶₁𝐵₂, 𝐵₁𝐴₂ равны углам треугольника 𝑋𝑌𝑍.

That hurt tech stocks. For the past few weeks, the 10-year yield has traded between 1.72% and 2%, as traders moved into the bond for safety when Russia headlines were ugly—and out of it when headlines improved. Now, the yield is touching its pandemic-era high. If the yield breaks above that level, that could signal that it’s on a sustainable path higher. Higher long-dated bond yields make future profits less valuable—and many tech companies are valued on the basis of profits forecast for many years in the future. The gold standard of encryption, known as end-to-end encryption, where only the sender and person who receives the message are able to see it, is available on Telegram only when the Secret Chat function is enabled. Voice and video calls are also completely encrypted. Perpetrators of these scams will create a public group on Telegram to promote these investment packages that are usually accompanied by fake testimonies and sometimes advertised as being Shariah-compliant. Interested investors will be asked to directly message the representatives to begin investing in the various investment packages offered. This provided opportunity to their linked entities to offload their shares at higher prices and make significant profits at the cost of unsuspecting retail investors.
